    So my never ending quest to get around RRV in under a minute continues. I managed to pop off a 1:01.026. I can manage 3 out of 5 laps to be 1:01xx. Now I need some help. The car seems to push a little when I turn in on some turns. I think if I correct that, something good will happen. The car is a [R]Dodge Concept Car hybrid with 958hp and it weighs 1924lbs. I have been slowly increasing downforce and making the gears longer until it seemed not to do any good but anyway, heres the current settings:

    Spring rate 15.8/14.7
    Ride Height 85/85
    Damper Bound 6/6
    Rebound 5/5
    Camber 1.6/1.3
    Toe -.05/.05 (this helped a lot)
    Stabilizer 1/4

    Brakes 14/24
    Downforce .44/.61
    LSD I 9
    LSD A 36
    LSD D 16

    Any help would be greatly appreciated.

    Well, as you are using a hybrid little help can probably be given in settings adjustment, but here's a tip incase you are cutting the corner in RRV: don't. It's only really faster with FF anf AWD cars.

    I will try your setting and see if I can improve it more. My initial suggestion would be:
    - use min front/max rear ride height to increase acceleration
    - use higher front damper
    - use gear trick mentioned in GT4 game guide
    - max downforce
    - zero camber, you don't need camber using spring rate that high.
    - increase your spring rate more if you use NTSC 1.2 version.

    in the mean time you can read how we can make a non hybrid Elise GT1 reach 0:58.933 here

    detail:
    1:03.xxx - if I spin
    1:01.xxx - if I can control the spin
    1:00.xxx - if I screw up some corner
    0:59.xxx - If I doing it save
    0:58.xxx - If I don't screw up
    0:55.xxx - perfect sector time using epsxe load & save

    Well as Toronado said, their not much you can do because it's a hybrid.
    But if you change a few things it should help, first change the ride height
    in the front so it's lower than the rear, this should help your car get upto
    speed faster. Next change the rear camber to a lower number because with
    that much hoserpower that too high a setting, try 0.5. One thing you could do
    is use a little more downforce, because with that much hoserpower it
    shouldn't hurt to have a little more downforce on your car. I hope this helps a bit.

    Edit:
    Yeah I still find it amazing how normal cars can go as fast or faster than a hybrid:).
    I think I got a 58:xxx on that track too, I should try it again to see if I have gotten better:mischievous:.

    I'm not cutting any corners. The car also bounces a lot in the first turn I dont know why. I'll try these adjustments soon. Thanks for the help guys. Any more replies are welcome too. :tup:

    Edit in case it matters:
    The car is on an AWD platform.

    Do you think you can get bellow 1 minute in non hybrid Dodge Concept car LM too?

    I only got this
    [​IMG]

    Boz Mon, since I don't know how you create that hybrid I just use concept car LM with this setting:
    Spring rate 20.0/20.0
    Ride Height 85/105
    Damper Bound 1/10
    Rebound 1/10
    Camber 0.0/0.0
    Toe 0/0
    Stabilizer 1/7

    gear is too complicated to explain.

    Downforce .78/.99
    LSD I 1
    LSD A 21
    LSD D 21

    TCS:51 (important)

    edit:
    you don't have to. you can get 58.xxx clean.
    ignore the bounce, you will be faster with max spring rate on first corner even when the car bouncing more.

    Not a bad time sucahyo:tup:, and any car will bounce in the first corner, it's
    the game, not your setup. Maybe you could tell us how you made your hybrid.

    Thats the thing, I dont know exactly what parts I used to make it because I made it back when GT2 was popular and everyone was making hybrids. All I know is its a 6 cylinder engine either supra or skyline, various engine parts, and FTO LM 4wd system. Thats about all I can tell you.

    Ok, I'm gonna try the settings now. I definately know that the car has a sub 1 minute lap in it. It will do 215mph by the end of the front straight. I'm starting to think that I just suck at driving.

    Edit: 1:01.05 (shakes head)

    I am sure you can do better AngelCreator, I use automatic :).

    Boz Mon, try to change the gearing, maybe move auto to 17 when you use 2.500 final drive

    I try this with stage 1 NA FTO LM hybrid (using previous setup):

    I think I have been going about this all wrong. I have been doing the RRV 5 lap championship race over and over. This got me a lot of money but not much progress. I have saved a ghost replay and have been chasing that around. Since then, my time has dropped to 1:00.141. Its kinda funny because in real life, I race go-karts and my dad always makes fun of me because I'm faster when I have someone to chase. I guess that works in virtual reality too. Hopefully, I'll get a better time soon. :scared:

    That how I work too, because if I have a time or a ghost the chase I will most of the time go faster.

    Indeed, I am giving up for tonight though. It's starting to get frustrating and my hand is starting to hurt. Tomorrow is another day...

    Edit: I know you guys say that its normal, but I am still getting this WICKED bounce on turns 1 and the last one, its so bad that sometimes it causes me to lose control and spin. Anyone have any suggestions?

    I believe its impossibe with an untuned GT-One.
    I got down to these:

    (((((HINT)))))

    Use ePSXe to save throughout each checkpoint of the race.

    In case anyone cares, I am now down to 1:00.063. This is starting to get tough. I know I can drive it and the car has it in it but it wont all come together. :grumpy:

    I know I wouldn't be able to do that (unless I play the game 10 hours a day).

    It will take a little work thats all, just keep working on it and you will get a good time:).

    @sucahyo
    I tried the concept car and I got a 1:01:4xx, I will get a pic later to show you.

    @usedHONDA
    Nice times:tup:.

    Edit:
    @Boz Mon
    About your bounce, i'm not sure how to fix it as I have the same problem.
    But if it helps try sucahyo's settings on your car, it might help.

    I still wouldnt mind some input on my settings. The car seems like it is fighting me on turn in. And that bounce is killer, I did kinda fix it though.

    AngelCreator, good time :).

    Boz Mon, just a bit more :). If your car spin because of bouncing, your car is not stable yet. If you can get the right balance, even when the car bouncing violently, your car would not spin. The easiest way to reduce bounce is by reducing spring rate.

    the theory behind why I use 1/10 1/10 damper is:
    For me 1 is stiffer than 10.
    during bouncing, car end with stiffer damper will has less grip then other end. by making front damper stiffer we can reduce car spin caused by bounce.

    edit:
    I failed to make FTO LM, concept LM to spin. Do you know any car that behave the same way as your car?

    Do you use PAL version ? if it is use spring rate no more than 12. PAL version bouce a lot more than NTSC 1.2 version.

    usedHONDA, try my setting, maybe you can improve your GT one time to 1:01.xxx range.

    I'm pretty sure that 10 is indeed stiffer than 1 because when I turned the dampers down, the car became more stable. Still not perfect but better.

    Do you have grand turismo original (GT1)? Try do that in GT1 and you can see the difference :).

    Use this:
    - max spring rate
    - max ride height
    - lowest stabilizer
    - stickiest tire

    drive around using damper 5 in GT1, then damper 1
    drive around using damper 10 in GT2, then damper 1

    you can try this in other simulation racing game too like viper racing, grand prix legend, etc.

    In GT1 and viper racing, where you can see damper effect more clearly, lowering damper will make your car bounce more. using max damper on both game will make the car skipping, not bouncing.

    If you need video to show the difference, I can make one :).

    I'm sorry, but no. While I am at a loss to explain GT1's damper adjustment, or GPL's (as I own niether); Viper Racing does not work that way. If you lower the damper stiffness alone, the car does not bounce more. It usually slides a bit more, but it does not bounce around as much. And I can make a video to prove it as well.

    The video upload may take a while, so I show preview first:

    soft damper
    [​IMG][​IMG]

    notice that the blue line indicating damper stiffness is perfectly flat, this is because I set the minimum damper value to 0, where default car usually set it to 5. maximum value for damper in default car usually 70.


    moderate damper

    Ok done, here is the video

    http://d.turboupload.com/d/1215427/rufctr_in_vr.avi.html

    if you can't see the video:
    on the first segment I use 0/0 0/0 damper. This should emulate how car react with soft damper equipped. during start on viper racing car usually dropped from certain height. At this moment we can already see how car keep bouncing up and down because damper do not stop suspension from moving. When the car driven the bouncing still exist, when turning in add the boucing force at one side of the car making it bouncing left and right.

    on the second segment I use 9/34 9/34 damper. This emulate how rebound usually stiffer than bound. during start we can see how car became quickly stable after dropped. when we launch the car, the body do not move too much and quickly stabilize by damper. During cornering you can see that car is stable too and you can clearly see how bad my driving skill is :p.

    So if I put the back rebound HIGHER (numerically) it will smoothe things out as far as reacting to bumps?

    In Viper Racing yes, but not in GT2 or GT4.

    If you experience too much bouncing in GT2 and GT4 lower your damper numeric value.

    in the same way, if you experiencing any lift off oversteer in GT2 or GT4, decrease you front bound damper numeric value.
